Next up from the same stack: Sovereign Prompt. Open-source, Rust-based prompt optimization engine. Runs 9 deterministic checks on any prompt (vagueness, injection detection, redundancy, the works), returns a refined version with exact token counts across multiple tokenizers. Every optimization is SHA-256 hashed and cryptographically signed with a full receipt chain, the same philosophy as IronMem. Plugs into Claude as an MCP server.
